  1. 1. A comparison of binaural recordings performed in six different room configurations

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Denice Perkhed; [2021]
    Keywords : Binaural recordings; absorbtion coefficient; reverberation time; anechoic chamber; listening test; Psychoacoustics; Technology and Engineering;

    Abstract : Children in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. READ MORE

  2. 2. Local Feature Correspondence on Side-Scan Sonar Seafloor Images

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Li Ling; [2021]
    Keywords : ;

    Abstract : In underwater environments, the perception and navigation systems are heavily dependent on the acoustic wave based sonar technology. Side-scan sonar (SSS) provides high-resolution, photo-realistic images of the seafloor at a relatively cheap price. READ MORE
